Subject: Skip Bison api.token.raw probe if Bison is not found.
X-Git-Tag: v1.3~66
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/eb7be85350a2dd971bb509e9191c33fc640cd0d5?hp=47a3f839901e933fa94f1f9afbd96a25fb539739

Skip Bison api.token.raw probe if Bison is not found.

Printing the api.token.raw probe when Bison was not found at all gives
strange configure output, let's just make the whole check conditional.
